UTG Universal Single-rail Shotgun Barrel Mount, 3 Slots , Black

Fits a Ruger MKII bull barrel perfectly and can be mounted right side up for a red dot etc. or upsidedown for a flashlight/laser combo. Great product and cones with 3 lengths of screws and the Allen key to install it. Worth the $11 for sure for my use.

I used it to attach a laser flashlight combo to my shotgun. It was easy to attach and seems to be quite solid. I am very happy with this product. I bought a second one for another shotgun.

No one makes rail mount for 20ga shotguns. But this solution from UTG seems to work. Have not done enough rounds to ensure it is not vibrating loose. But in theory the clamping design should be good as long as you use loctite with the screws. Don't over tighten and maintain a gap between the two clamp pieces. The only issue is by design it cannot mount at true 3 and 9 o'clock to avoid the sling covering part of the light. But for the money and availability you can't beat it. Will update if the mount gets loose after a few hundred rounds.

Fits the mossberg maverick 88 very well and tight! I have the 18.5 so I don't have the extended tube. So it fits just right. I needed a picatinny rail, so I can add a flashlight mount. It came with the extra screws too. You can't beat the price, and this thing is tough and rugged.

All good. It's what I needed for a red dot. Light but very stable.

Received in two days, looks and feels like a quality product. Time will tell. Mounted on the barrel on my 12 gauge Mossberg 590 A1 with ghost ring sights with an 18 inch barrel. This model shotgun has a rife type front post, so there is very little room to mount the unit. It just barely fits, however with one caveat. Once installed, you will have to remove it if you want to take the end screw cap off that holds the barrel on. No big deal. It came with different length screws to accommodate different diameter barrels. Finish was excellent, threads both male and female are very good, no sharp edges on the unit. Packing was adequate and proper protective oil was applied. I was impressed with the product and plan to buy one of their tactical flashlights and give that a try too. I think this product would be good around the house and or farm. It doesn't claim to be Mill spec.

For many people using shotguns for home defense, buying a "cool guy" black tactical shotgun with all of the rails and trimmings may be a little much. Plus it's not necessary. It is necessary however to see what you're shooting it. So, if you're like me and want to use a basic model shotgun for home defense, buy this mount for the magazine tube and attach your favorite light.This mount fits wonderfully on a Mossberg 500. It has just enough room between the end of the tube and top of the forestock. The four screws fit tightly with an Alan wrench. Simple and effective.The only downside is that you will have to remove this mount every time you are field stripping the shotgun, as most forestocks are removed by pulling them off from the magazine tube. Still, a great product for a shotgun that may not be fired that often and is simply guarding a home.

Ordered one of these mounts and was a little worried about how solid it would be, to my supprise it worked out great on my Remington 870 12 gauge. Mounted on the barrel and appears to be very solid, added a little blue threadlocker and I was ready to mount some left over iron sights from an AR platform I use to own. Liked the product so much I just ordered another one to mount a flashlight on the bull barrel of my Ruger Mark II critter getter.
